Abstract

A heat-insulating container comprises a paper cup body having an inner surface, an upper open end, a shell member and a bottom, the inner surface being coated with polyolefine resin, the upper open end having an outward curled portion and the shell member having a side wall on which at least one rib is formed; and a tubular member being formed of paper and having an inverse truncated conical shape, the tubular member having at a lower end thereof an inward curled portion. The tubular member is combined with an outer periphery of the paper cup body so as to come into contact with the paper cup body in contact portions provided on the at least one rib of the paper cup body and on an outer periphery of an lower end of the side wall of the shell member. According to such a structure, it is possible to provide the heat-insulating container, which has a stable heat-insulating property, a high grade design, a high degree of freedom in indication by printing on the outer surface of the container, and a lower production cost.

Description

The present invention relates to a heat-insulating container made of paper, which is used for an instant dried food to be become eatable by pouring boiling water over it or food to be heated or cooked by means of a microwave oven.As a heat-insulating container made paper mainly used for instant dried Chinese noodles, there has widely been used a container in which a paper cup body surrounded over its outer periphery with a heat-insulating corrugated member having narrow projections and recesses arranged alternately.The heat-insulating member of the heat-insulating container has the above-mentioned irregularity so that characters, designs or the like printed on its surface appear extremely unclearly, thus making it impossible to give the high-grade appearance of design to the container.In Japanese Patent Provisional Publication No. H8-113274, there is proposed a heat-insulating container in which the width of the recesses of the heat-insulating member is made smaller than that of the...
